“…The hybrid RANS/LES methods, represented by delayed detached eddy simulation (DDES), adopt the RANS method near the wall and adopt the LES method in the detached region, which obtains considerable accuracy with moderate computational cost. The hybrid RANS/LES methods have been used for more and more applications in recent years [3][4][5].…”

Flow noise is an important issue of underwater vehicles. In this paper, the ability of different numerical methods to predict the flow noise of the DARPA SUBOFF underwater vehicle model is investigated and compared. It is found that the front of the command deck and the tail fins are the main noise sources. Numerical results show that delayed detached eddy simulation is a suitable computational model for flow noise simulations.

“…The method of empirical formula estimation has practical uses, but its accuracy is not assured. Model testing is a more precise method, but cost and mechanism functionality limitations make obtaining a complete set of hydrodynamic force coefficients challenging [4]. CFD technology enables the numerical simulation of all the movements of the model, significantly reducing cost and cycle time, but the calculation accuracy of complex movements requires investigation [5].…”

To ensure optimal maneuvering performance of underwater vehicles, it is essential to obtain highly precise hydrodynamic coefficients for constructing the equations of motion. The principal approach to acquiring these coefficients is through the Planar Motion Mechanism (PMM) test. The subject of this paper is the SUBOFF full appendage model. To obtain hydrodynamic coefficients related to maneuvering motion, a Vertical Planar Motion Mechanism (VPMM) test is conducted in the circulating water tank. In addition, a numerical simulation of the typical pure heaving and pure pitching maneuverability test is performed for the model by programming its motion UDF using Fluent’s dynamic mesh technology. The test results and calculated hydrodynamic coefficients are compared to the data obtained from the Key Laboratory of Underwater Robotics Technology of Harbin Engineering University. The calculation results show high credibility of the test results of the circulating tank VPMM test. The corresponding numerical simulation has a certain practical engineering accuracy, which can break through the limitations of the test and also provides valuable experience and technical reference for the hydrodynamic prediction of other underwater vehicles.

“…The turning ability of a submarine with the X-rudder plane configuration and virtual propeller has been predicted through numerical simulation of turning circles with different deflection of the rudders in Star-CMM+ code in [17]. The complex fluid flow around the DARPA SUBOFF submarine with rudder deflection has been analyzed based on OpenFOAM [18], where the hydrodynamic forces and moments of the rudder with a wide range of deflection angles were calculated and compared with experimental data. The forward running of a submarine near the free water surface has been simulated using Ansys Fluent code to predict the resistance of the hull under the Cross-rudder plane configuration, as well as the thrust and torque of the propeller [19].…”

This study presents the predicted hydrodynamic characteristics of different rudder plane configurations on the stern of a full-scale submarine in deep water, which are obtained using the Reynolds-Averaged Navier–Stokes method in Ansys Fluent Solver. First, the results obtained for the X-rudder plane configuration are verified according to previous numerical and experimental results in order to assess the accuracy of the simulation procedure. The X-rudder plane, Y-rudder plane, and Cross-rudder plane configurations in deep water with deflection angles ranging from −21 degrees to +21 degrees are then simulated. Next, the hydrodynamic forces and moments of the Cross-plane, X-plane, and Y-plane rudder configurations obtained through simulation are analyzed using Taylor’s expansion to estimate the hydrodynamic coefficients. The obtained results demonstrate that the X-force of the X-plane rudder configuration is larger than the corresponding forces acting on the Cross-plane rudder and Y-plane rudder configurations. Meanwhile, the Y-force and Z-force of the X-plane rudder configuration are significantly greater than the corresponding forces of the left configurations. The same tendency can be seen in the moment of the X-plane rudder about the y- and z-axes. However, the roll moment induced by the Y-plane and Cross-plane rudder configurations is significantly larger than that under the X-plane rudder configuration.
